Three Tennessee counties have been quarantined for Emerald Ash Borer (EAB) after detection of the forest-devastating insect, bringing the total number of Tennessee counties under a state and federal EAB quarantine to 62. Cheatham, Giles, and Maury counties have been added to the list of areas restricted for the movement of firewood, ash nursery stock, ash timber, and other material that can spread EAB. The tree-killing beetle was recently found in these three counties through the United States Department of Agriculture’s EAB detection program.

Last year, the TVA found water hyacinth in a slough near Scottsboro. TVA quickly partnered with the State of Alabama, bringing experts from both sides to start addressing the invasive water weed. Water hyacinth is bad news for Guntersville and other great fisheries in the Tennessee Valley. The plant can quickly outcompete other beneficial plants, often creating biological wastelands. Hartis and his team are asking the public to be on the lookout for hyacinth this summer. “If you see a [hyacinth] plant, pull it out of the water immediately and put it in the trash. We don’t want plants to float to a new area and establish a new colony.” If you find a large area of hyacinth, please report it to TVA's Public Land Information Center at (800) 882-5263 (between 8 a.m. and 6 p.m. Eastern).

A plant disease that presents a serious threat to the U.S. citrus industry has been detected in Alabama. Federal and state plant health officials have confirmed the identification of citrus greening (CG), also known as Huanglongbing or HLB, which is caused by the bacterial pathogen Candidatus Liberibacter asiaticus. This is the first confirmation of citrus greening in Alabama despite biannual surveys for the pathogen by the Alabama Department of Agriculture and Industries (ADAI).
